這篇文章主要介紹了php實現模擬登陸方正教務系統抓取課表的相關資料,需要的朋友可以參考下
課程格子和超級課程表這兩個應用,想必大學生都很熟悉,使用自己的學號和教務系統的密碼,就可以將自己的課表導入,隨時隨地都可以在手機上查看。
其實稍微了解一點php的話,我們也可以做一個類似這樣的web 應用。
1,解決掉驗證碼
其實這是正方的一個小bug,當我們進入登陸界面時,瀏覽器會去請求服務器,服務器會生成一個驗證碼圖片。如果我們不去請求這個圖片,那么正方后臺也不會生成相應的 驗證碼,于是這樣我們就有了可乘之機,讓我高興會兒~這時,我們在不填寫驗證碼的情況下,可以很流暢的進入。大家可以在自己的電腦上禁止訪問驗證碼的地址,然后試試這 是不是真的~當然,這只對正方有效。
2,php 的curl 模擬登陸
接下來就是相關代碼了,相信很多人和我一樣,只喜歡看例子,對于長篇大論的講解,轉頭就走……不過這個習慣還是不好……廢話不多說!
- //模擬登陸
- function curl_request($url,$post='',$cookie='', $returnCookie=0){
- $curl = curl_init();
- curl_setopt($curl, CURLOPT_URL, $url);
- curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0)');
- curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
- curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
- curl_setopt($curl, CURLOPT_REFERER, "這里一定要換成教務系統登陸的url"); //填寫教務系統url
- if($post) {
- curl_setopt($curl, CURLOPT_POST, 1);
- curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post));
- }
- if($cookie) {
- curl_setopt($curl, CURLOPT_COOKIE, $cookie);
- }
- curl_setopt($curl, CURLOPT_HEADER, $returnCookie);
- curl_setopt($curl, CURLOPT_TIMEOUT, 20);
- curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
- $data = curl_exec($curl);
- if (curl_errno($curl)) {
- return curl_error($curl);
- }
- curl_close($curl);
- if($returnCookie){
- list($header, $body) = explode("/r/n/r/n", $data, 2);
- preg_match_all("/Set/-Cookie:([^;]*);/", $header, $matches);
- $info['cookie'] = substr($matches[1][0], 1);
- $info['content'] = $body;
- return $info;
- }else{
- return $data;
- }
- }
3,教務系統登陸頁面的隱藏字段
舉個栗子
復制代碼代碼如下:
- <input type="hidden" name="__VIEWSTATE" value="dDwyODE2NTM0OTg7Oz61eIbnKVojBioGYtg2vsy2SklwiA==">
這些東西在登陸的時候也是需要帶上的,順便貼出函數,順便暴漏了博主的學校……皇家種地大學(主要是正則表達式的運用)
- //登陸頁面的隱藏字段
- function getView(){
- $url = 'http://jw.hzau.edu.cn/default2.aspx';
- $result = curl_request($url);
- $pattern = '/<input type="hidden" name="__VIEWSTATE" value="(.*?)" //>/is';
- preg_match_all($pattern, $result, $matches);
- $res[0] = $matches[1][0];
- return $res[0] ;
- }
- //返回教室查詢頁面的隱藏值
- private function getViewJs($cookie,$xh){
- $url = "http://jw.hzau.edu.cn/xxjsjy.aspx?xh={$xh}";
- $result = curl_request($url,'',$cookie);
- $pattern = '/<input type="hidden" name="__VIEWSTATE" value="(.*?)" //>/is';
- preg_match_all($pattern, $result, $matches);
- $res[0] = $matches[1][0];
- return $res[0] ;
- }
4,cookie 的獲取
- function login($xh,$pwd){
- $url = 'http://jw.hzau.edu.cn/default2.aspx';
- $post['__VIEWSTATE'] = $this->getView();
- $post['txtUserName'] = $xh; //填寫學號
- $post['TextBox2'] = $pwd; //填寫密碼
- $post['txtSecretCode'] = '';
- $post['lbLanguage'] = '';
- $post['hidPdrs'] = '';
- $post['hidsc'] = '';
- $post['RadioButtonList1'] = iconv('utf-8', 'gb2312', '學生');
- $post['Button1'] = iconv('utf-8', 'gb2312', '登錄');
- $result = curl_request($url,$post,'', 1);
- return $result['cookie'];
- }
5,讓我們來試試查課表的功能,格式有點亂額,大家湊合著看,我把課表轉成了一個二維關聯數組
- //返回課表字符串
- private function classresult($xh,$pwd){
- date_default_timezone_set("PRC"); //時區設置
- $classList = "";//聲明課表變量
- $cookie = $this->login($xh,$pwd);
- $view = $this->getViewJs($cookie,$xh);//驗證密碼是否正確
- //如果密碼正確
- if (!emptyempty($view)) {
- $url = "http://jw.hzau.edu.cn/xskbcx.aspx?xh={$xh}";
- $result = curl_request($url,'',$cookie); //保存的cookies
- preg_match_all('/<table id="Table1"[/w/W]*?>([/w/W]*?)<//table>/',$result,$out);
- $table = $out[0][0]; //獲取整個課表
- preg_match_all('/<td [/w/W]*?>([/w/W]*?)<//td>/',$table,$out);
- $td = $out[1];
- $length = count($td);
- //獲得課程列表
- for ($i=0; $i < $length; $i++) {
- $td[$i] = str_replace("<br>", "", $td[$i]);
- $reg = "/{(.*)}/";
- if (!preg_match_all($reg, $td[$i], $matches)) {
- unset($td[$i]);
- }
- }
- $td = array_values($td); //將課程列表數組重新索引
- $tdLength = count($td);
- for ($i=0; $i < $tdLength; $i++) {
- $td[$i] = iconv('GB2312','UTF-8',$td[$i]);
- }
- //將課表轉換成數組形式
- function converttoTable($table){
- $list = array(
- 'sun' => array(
- '1,2' => '',
- '3,4' => '',
- '5,6' => '',
- '7,8' => '',
- '9,10' => ''
- ),
- 'mon' => array(
- '1,2' => '',
- '3,4' => '',
- '5,6' => '',
- '7,8' => '',
- '9,10' => ''
- ),
- 'tues' => array(
- '1,2' => '',
- '3,4' => '',
- '5,6' => '',
- '7,8' => '',
- '9,10' => ''
- ),
- 'wed' => array(
- '1,2' => '',
- '3,4' => '',
- '5,6' => '',
- '7,8' => '',
- '9,10' => ''
- ),
- 'thur' => array(
- '1,2' => '',
- '3,4' => '',
- '5,6' => '',
- '7,8' => '',
- '9,10' => ''
- ),
- 'fri' => array(
- '1,2' => '',
- '3,4' => '',
- '5,6' => '',
- '7,8' => '',
- '9,10' => ''
- ),
- 'sat' => array(
- '1,2' => '',
- '3,4' => '',
- '5,6' => '',
- '7,8' => '',
- '9,10' => ''
- )
- );
- $week = array("sun"=>"周日","mon"=>"周一","tues"=>"周二","wed"=>"周三","thur"=>"周四","fri"=>"周五","sat"=>"周六");
- $order = array('1,2','3,4','5,6','7,8','9,10');
- foreach ($table as $key => $value) {
- $class = $value;
- foreach ($week as $key => $weekDay) {
- $pos = strpos($class,$weekDay);
- // echo $pos;
- if ($pos) {
- $weekArrayDay = $key; //獲取list數組中的第一維key
- foreach ($order as $key => $orderClass) {
- $pos = strpos($class,$orderClass);
- if ($pos) {
- $weekArrayOrder = $orderClass; //獲取該課程是第幾節
- break;
- }
- }
- break;
- }
- }
- $list[$weekArrayDay][$weekArrayOrder] = $class;
- }
- return $list;
- }
- //調用函數
- return converttoTable($td);
- }else{
- return 0;
- }
- }
6,再試試查詢空教室的功能
- //空教室查詢結果
- public function roomresult(){
- $xh = ""; //設置學號
- $pwd = ""; //學號對應的密碼
- $cookie = $this->login($xh,$pwd);
- $url = "http://jw.hzau.edu.cn/xs_main.aspx?xh={$xh}";
- $result = curl_request($url,'',$cookie); //保存的cookies
- $url="http://jw.hzau.edu.cn/xxjsjy.aspx?xh={$xh}";
- $post['Button2'] = iconv('utf-8', 'gb2312', '空教室查詢');
- $post['__EVENTARGUMENT']='';
- $post['__EVENTTARGET']='';
- $post['__VIEWSTATE'] = $this->getViewJs($cookie,$xh);
- $post['ddlDsz'] = iconv('utf-8', 'gb2312', '單');
- $post['ddlSyXn'] = '2014-2015'; //學年
- $post['ddlSyxq'] = '1';
- $post['jslb'] = '';
- $post['xiaoq'] = '';
- $post['kssj']=$_GET['start']; //提交的開始查詢時間
- $post['sjd']=$_GET['class'];//提交的課程節次
- $post['xn']='2014-2015';//所在學年
- $post['xq']='2';//所在學期
- $post['xqj']='6';//當天星期幾
- $post['dpDataGrid1:txtPageSize']=90;//每頁顯示條數
- $result = curl_request($url,$post,$cookie,0);
- preg_match_all('/<span[^>]+>[^>]+span>/',$result,$out);
- $tip = iconv('gb2312', 'utf-8', $out[0][3]);//獲取頁面前部的提示內容
- preg_match_all('/<table[/w/W]*?>([/w/W]*?)<//table>/',$result,$out);
- $table = iconv('gb2312', 'utf-8', $out[0][0]); //獲取查詢列表
- $this->load->view("classroom",array('tip'=>$tip,'table'=>$table));
- }
總結起來就是這些了,每個學校的教務系統都不盡相同,這時我們可以借助火狐瀏覽器的 firebug 抓包,看看到底提交了哪些東西。
